Answer:
r=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−4(r+2)=4(2−2r)
Step 1: Simplify both sides of the equation.
−4(r+2)=4(2−2r)
(−4)(r)+(−4)(2)=(4)(2)+(4)(−2r)(Distribute)
−4r+−8=8+−8r
−4r−8=−8r+8
Step 2: Add 8r to both sides.
−4r−8+8r=−8r+8+8r
4r−8=8
Step 3: Add 8 to both sides.
4r−8+8=8+8
4r=16
Step 4: Divide both sides by 4.
4r
4

<u>Answer</u>: If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.
<u>Step-by-step explanation</u>:
Let x be the customer's total amount.
It is given that 15% of the customer's total = $22.05
⇒15% of x= $22.05

Therefore, If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.
Answer:
The interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
Step-by-step explanation:
The confidence interval is the interval estimate of the population parameter.
The confidence interval has a certain probability that the true value of the parameter is contained in the interval.
The general form of the confidence interval is:

Here,
SS = sample statistic.
MOE = margin of error
The sample statistic is an unbiased estimator of the population parameter. If the sample size is large enough then the sample statistic can be used to estimate the population parameter value.
In this case the parameter of interest is the population proportion of American adults who got their health insurance from an employer.
The information provided is:
<em>SS = p = </em>0.45.
<em>MOE</em> = 0.02.
Compute the confidence interval for the population proportion <em>p</em> as follows:

Thus, the interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
Answer:
f(x) = 3(2)^x
Step-by-step explanation:
The Table is:
<u>x</u> <u>f(x)</u>
-2 3/4
-1 3/2
0 3
1 6
2 12
The exponential funtion has the next form:
f(x) = a(b)^x
At x = 0, f(x) = a. Then, a = 3
Isolating b from the equation:
f(x)/a = b^x
ln(f(x)/a) = x*ln(b)
[ln(f(x)/a)]/x = ln(b)
At x = 1, f(x) = 6. Then:
[ln(6/3)]/1 = ln(b)
ln(2) = ln(b)
2 = b
Therefore, the function is f(x) = 3(2)^x
